Check out the Casio forum at www.dpreview.com It is much more active than this forum and pictures are posted regularly. Also their are lots of Z750 users there. Where are you located geographically?
Give it a try.

I live in Troy, Michigan. The problem with the dpreview forum is that to register they require an email address other than those that are web based and I don't have one of those that I regularly use. Would you like to be my mentor? I will send you my latest pics and you can challenge me with your critiques. I would love that.
